remove file extention and artist from title

Search engines improvement. Songs title parser to extract clean song title from string title in form "artist"+'-'+"title" to pass clean title to lyrics search engine. With out this option the search is unsuccessful. I thing that the generally that will be good idea that if IDTag fields (artist and title) the parser will find any special character like '+', '-', '&' will give possibility to select and search part of field in related to field window. The additional improvement is to search and propose artist and album name based on title.
